27 ;; This lisp code is a general framework for translating various
28 ;; representations of the same data.
29 ;; among other things it can be used to translate TeX, HTML, and compressed
30 ;; files to ISO 8859-1. It can also be used to translate different charsets
31 ;; such as IBM PC, Macintosh or HP Roman8.
32 ;; Note that many translations use the GNU recode tool to do the actual
33 ;; conversion. So you might want to install that tool to get the full
34 ;; benefit of iso-cvt.el
37 ; Cover more cases for translation. (There is an infinite number of ways to
38 ; represent accented characters in TeX)
41 ; If you are interested in questions related to using the ISO 8859-1
42 ; characters set (configuring emacs, Unix, etc. to use ISO), then you
43 ; can get the ISO 8859-1 FAQ via anonymous ftp from
44 ; ftp.vlsivie.tuwien.ac.at in /pub/8bit/FAQ-ISO-8859-1
